<h1 id="gtk-4-tutorial-for-beginners">GTK 4 Tutorial for beginners</h1>
<h4 id="contents-of-this-repository">Contents of this Repository</h4>
<p>This tutorial illustrates how to write C programs with the GTK 4
library. It focuses on beginners so the contents are limited to the
basics. The table of contents is at the end of this abstract.</p>
<ul>
<li>Section 3 to 21 describes the basics, with the example of a simple
editor <code>tfe</code> (Text File Editor).</li>
<li>Section 22 to 25 describes GtkDrawingArea.</li>
<li>Section 26 to 30 describes the list model and the list view
(GtkListView, GtkGridView and GtkColumnView). It also describes
GtkExpression.</li>
</ul>
<p>The latest version of the tutorial is located at <a
href="https://github.com/ToshioCP/Gtk4-tutorial">GTK4-tutorial GitHub
repository</a>. You can read it directly without download.</p>
<p>There’s a GitHub Page of this tutorial at <a
href="https://toshiocp.github.io/Gtk4-tutorial/"><code>https://toshiocp.github.io/Gtk4-tutorial/</code></a>.
It is easier to read than the repository.</p>
<h4 id="gtk-4-documentation">GTK 4 Documentation</h4>
<p>Please refer to <a href="https://docs.gtk.org/gtk4/index.html">GTK 4
API Reference</a> and <a href="https://developer.gnome.org/">GNOME
Developer Documentation Website</a> for further information.</p>
<p>These websites were opened in August of 2021. The old documents are
located at <a href="https://developer-old.gnome.org/gtk4/stable/">GTK
Reference Manual</a> and <a
href="https://developer-old.gnome.org/">GNOME Developer Center</a>.</p>
<p>If you want to know about GObject and the type system, please refer
to <a href="https://github.com/ToshioCP/Gobject-tutorial">GObject
tutorial</a>. GObject is the base of GTK 4, so it is important for
developers to understand GObject as well as GTK 4.</p>
<h4 id="contribution">Contribution</h4>
<p>This tutorial is still under development and unstable. Even though
the codes of the examples have been tested on GTK 4 (version 4.8.1),
bugs may still exist. If you find any bugs, errors or mistakes in the
tutorial and C examples, please let me know. You can post it to <a
href="https://github.com/ToshioCP/Gtk4-tutorial/issues">GitHub
issues</a>. You can also post updated files to <a
href="https://github.com/ToshioCP/Gtk4-tutorial/pulls">pull request</a>.
One thing you need to be careful is to correct the source files, which
are under the ‘src’ directory. Don’t modify the files under
<code>gfm</code> or <code>html</code> directories. After modifying some
source files , run <code>rake</code> to create GFM (GitHub Flavoured
Markdown) files and run <code>rake html</code> to create HTML files.</p>
<p>If you have a question, feel free to post it to <code>issue</code>.
All questions are helpful and will make this tutorial get better.</p>
<h4 id="how-to-get-gtk-4-tutorial-with-html-or-pdf-format">How to get
Gtk 4 tutorial with HTML or PDF format</h4>
<p>If you want to get HTML or PDF format tutorial, make them with
<code>rake</code> command, which is a ruby version of make. Type
<code>rake html</code> for HTML. Type <code>rake pdf</code> for PDF.
There is a document (“<a href="Readme_for_developers.html">How to build
GTK 4 Tutorial</a>”) for further information.</p>
